Richards helped lead the Lightning to their only Stanley Cup title in 2004, collecting 26 points in 23 playoff games and earning the Conn Smythe Trophy as MVP of the postseason. He also helped the Blackhawks to a Stanley Cup title in 2015.

"I want to thank the fans and the five organizations I have played for: Tampa Bay, Dallas, and the three Original Six teams -- the New York Rangers, Chicago, and Detroit," Richards said in a statement put out by the NHLPA. "During my time with those teams I met many great people. I also want to thank the staff and management in those organizations for all the help and support they gave me. I appreciate all the trainers who did tireless work to help me play and keep me healthy. I had many amazing teammates and made many great friendships along the way that I truly appreciate, and I will never forget the great times we had together. Thank you to all my coaches for pushing, teaching and giving me the opportunity to play this great game. Winning the Stanley Cups in Tampa Bay and Chicago was the best part of my career and I will never forget those moments. Nothing compares to enjoying that night with your team and knowing what you have accomplished together."
